shoes to form an elastic trea forthe same.

A further object is to provide means in combination with the cushion whereby the shoe will be ventilated.

- ,With the above and other objects in view the'invention consists of certain novel features of construction, combination, arr .2;-

. rangeinent of parts, as will be hereinafter de- '2 5 scribed and claimed.

In the accompanying drawings, Figure 1 is a plan view of a heel-insole, showing the arrangement'of the ventilating-apertures. Fig. 2 is a longitudinal vertical sectional view of the saine and the heelcushion attached thereto. Fig. 3 is a plan view of one sideo'f the cushion. Figj 4 is a similar view of the opposite side of the cushion, and Fig. 5' is a longitudinal vertical sectional view of the cushion.

heel of the shoe, which is constructed in the usual manner. Where the cushion-plate 4 is stitched to the heel-insole the same is beveled or tapered to an edge, the inner end of the insole-plate being also tapered or beveled, as shown, thus providing for a gradual rise from the sole portion of the shoe to the cushion portion in the heel of the same, so that when the cushion is arranged in the heel of the shoe no unevenness: of the insole Will be perceptible.

By the use of a heel cushion constructed and arranged as herein show 11 and described the shoe inay 'oe worn with greater ease and comfort and a ventilation oi the same will be provided for.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the Form, proportion, and the minor details of constrsction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

A heel-cushion consisting of a rubber cush ion-plate having formed on its under side a series of hollow, imperforate, i'rusto-conical projections, said rubber plate having a series of ventilating-openings intermediate the projections, a superposed insole layer provided with a series of perforations and extending backward beyond the cushion-plate, and a lining-strip, said cushion-plate and insole layer being tapered at their front ends and secured together by a line of stitching, said insole layer being secured above the rubber cushion-plate, and the lining-strip disposed below said cushion-plate, substantially as described.

In testimony whereof we have-hereunto set our hands in presei'ice of two subscribing JULIUs CALMANN, HENRY THOMAS.
